Walk down any sleep aisle. Every bottle, every gummy, every tincture is built on one assumption: you sleep at night. They were never designed for the nurse coming off a 12-hour graveyard, the warehouse worker pulling rotating shifts, or the truck driver who slept twice yesterday.

When you sleep during the day, sunlight floods your brain's master clock — the suprachiasmatic nucleus — which suppresses melatonin and keeps cortisol elevated. A standard sleep gummy doesn't address this. PostShift was engineered to.

Every melatonin pill on the market addresses one symptom: a missing sleep signal. But shift work breaks sleep in four separate ways — elevated cortisol from your shift, suppressed natural melatonin from daylight exposure, an over-activated nervous system, and shift-specific nutritional deficiencies that build up over months.

One ingredient can't solve a four-part problem. PostShift uses 7 active ingredients — each at a clinical dose, each addressing a specific cause. Not a "sleep blend." Not fairy dust. Seven precise tools, working together.

Most sleep pills don't help you sleep. They override your body's ability to do it. The more you take, the less your body produces on its own. That's why you keep needing more — and why some nights nothing seems to work.

PostShift was built differently. The dose is calibrated to support your natural rhythm, not replace it. The other 6 ingredients work with your biology — calming cortisol, easing your nervous system, replenishing what your schedule has been depleting. Your body does the sleeping. PostShift just clears the path.

Here's what nobody tells you: when you try to sleep during the day, your cortisol is still elevated from your shift. Your body thinks it should be alert. No melatonin pill in the world will work if your stress hormones are still raging.

PostShift uses 600mg of standardized Ashwagandha Root Extract (5% withanolides) — twice the dose most sleep aids include, if they include it at all. Clinical research has consistently shown that ashwagandha at this dose reduces cortisol levels, calming the system that's keeping you wired when you should be winding down.

Apigenin is the compound found in chamomile that's responsible for its calming effects — except in chamomile tea, you'd need to drink gallons to get a meaningful dose. PostShift includes 50mg of pure Apigenin in every serving.

It works by gently activating GABA receptors — the same calming pathway prescription sleep medications target, but without the sedative knockout. The result: a quiet mind, a slower heart rate, and the kind of natural drowsiness that lets you fall asleep instead of forcing you unconscious.

Glycine is one of the most researched sleep ingredients in the world — and almost nobody puts it in their formula because it's harder to source and doesn't sound exciting. Japanese sleep researchers have studied it for decades.

It works by lowering your core body temperature — the exact physiological shift your body needs to fall into deep sleep. People who take glycine before bed report feeling more refreshed the next day and getting deeper, more restorative sleep. PostShift uses the full clinical dose: 500mg per serving.

Most sleep gummies and supplements use magnesium oxide. It's cheap, it's everywhere, and your body absorbs only about 4% of it. The other 96% gives you stomach issues and ends up in the toilet.

PostShift uses Magnesium Bisglycinate Chelate — the chelated form that's roughly 80% bioavailable. It relaxes your muscles after a long shift, calms your nervous system, and won't wreck your stomach. The form matters more than the dose.
